KAIRA (Kilpisjärvi Atmospheric Imaging Receiver Array)
is a project of the Sodankylä Geophysical Observatory.
KAIRA is a dual array of omni-directional VHF radio antennas, principally
funded by the University of Oulu in
Finland. It makes extensive use of the proven LOFAR antenna and digital signal-processing
hardware, and can act as either a stand-alone passive receiver, as a receiver
for the EISCAT VHF incoherent scatter radar
in Tromsø, or for use in conjunction with other Fenno-Scandinavian VHF
experiments. In additional to being a powerful observing instrument in its
own right, KAIRA acts as a pathfinder for technologies used in the
proposed EISCAT_3D radar system.
